Abstract

L'invention concerne un spectromètre à mobilité ionique et à champ asymétrique (100) comprenant : une source d'ionisation (10) utilisée pour produire des ions ; une plaque d'électrode (20) ; une pluralité de fils d'électrode (40), les fils d'électrode (40) et la plaque d'électrode (20) étant agencés de manière opposée et étant séparés par un espace d'analyse (d), un champ électrique haute tension étant situé entre la plaque d'électrode (20) et la pluralité de fils d'électrode (40), ce qui permet de former une zone de mobilité ionique (R), et les fils d'électrode étant utilisés pour collecter des ions ne passant pas à travers la zone de mobilité ionique (R) ; et une électrode de collecte (60), disposée à une extrémité arrière de la zone de mobilité ionique (R) et utilisée pour collecter les ions passant à travers la zone de mobilité ionique (R). Le spectromètre à mobilité ionique et à champ asymétrique (100) améliore la précision de l'identification de la position du pic d'ion, et réduit le temps de balayage de la tension de courant continu et les types de tension de compensation, ce qui permet d'améliorer l'efficacité de la détection d'ion.
